Looking to build a pc within the next month, and have a 1000 pound budget, but would be better if it could be lower as possible. I will be playing Csgo competitively and LoL too, so a high refresh rate monitor is needed, and I may be playing some other high end games such as gta, fallout etc. I would like the build to include the monitor, mouse, keyboard (preferably mechanical) and obviously the pc too (no os). Thanks in advance (will be streaming and editing a lot too).
